Removed stdio structure ops support on arm_dcc
driver, and need to register with serial core
so-that it can access like remianing serial drivers.

10ec0f8a74 serial: arm_dcc: Fix compilation warning and remove unneeded initialization
- arm_dcc_dev is already initialized.
- Remove unused rc variable
Warning log:
arm_dcc.c: In function 'drv_arm_dcc_init':
arm_dcc.c:145:6: warning: unused variable 'rc' [-Wunused-variable]

e70fb539a6 serial: arm_dcc: Remove CONFIG_ARM_DCC_MULTI option
CONFIG_ARM_DCC_MULTI should be also removed in the patch
"serial: Remove CONFIG_SERIAL_MULTI from serial drivers"
(sha1: a382725060)
Because the driver defines serial_* functions
which cause conflict with serial.c (multiple definition of serial_*)

Removing CONFIG_SERIAL_MULTI function also require to define
default_serial_console for cases where another serial driver
is not available in the system.

52cb4d4fb3 stdio/device: rework function naming convention
So far the console API uses the following naming convention:

	======Extract======
	typedef struct device_t;

	int	device_register (device_t * dev);
	int	devices_init (void);
	int	device_deregister(char *devname);
	struct list_head* device_get_list(void);
	device_t* device_get_by_name(char* name);
	device_t* device_clone(device_t *dev);
	=======

which is too generic and confusing.

Instead of using device_XX and device_t we change this
into stdio_XX and stdio_dev

This will also allow to add later a generic device mechanism in order
to have support for multiple devices and driver instances.

4f5728987f arm: add uart dcc support
Serial driver via the EmbeddedICE macrocell's DCC channel using
co-processor 14.

It does include a timeout to ensure that the system does not
totally freeze when there is nothing connected to read.
